AUTISM ASSESSMENTS London
We offer Gold-Standard Autism assessments in London
providing comprehensive, evidence-based evaluations for children, adolescents, and adults. Our assessments follow the highest clinical standards, ensuring accurate and reliable diagnoses that are widely accepted by the NHS and other healthcare providers.
An autism diagnosis can be life-changing, providing a clearer understanding of strengths, challenges, and support needs. However, obtaining a high-quality ASC (Autism Spectrum Condition) assessment is essential to ensure accuracy and thoroughness.

Why chOOSE our AUTISM assessmentS?
At Sage Psychology, our Autism assessments in London adhere to the highest standards of practice, meeting the guidelines set out by the National Institute for Health and Care excellence (NICE).
What Makes a High-Quality Autism Assessment?
NICE guidelines state that Autism assessments for children should include the following:
A detailed developmental history
We explore behavioural and developmental patterns consistent with ICD-11 or DSM-5 criteria, using autism-specific tools where appropriate.
A thorough review of concerns
We interact with and observe the individual, focusing on traits associated with autism, using standardised diagnostic tools.
Direct assessment of social and communication skills
More than one clinician reviews the findings before confirming a diagnosis, ensuring a rigorous process.
Medical and family history analysis
We review prenatal, perinatal, and past health conditions. A physical examination may be required via referral to your GP.
Consideration of differential diagnoses
We assess whether autism best explains the individual’s experiences or if another condition may be a better fit.
Screening for co-occurring conditions
Many individuals with autism also experience anxiety, ADHD, or sensory processing challenges, which we systematically assess.
Strengths-based profiling
Beyond diagnosis, we create a personalised report outlining strengths, challenges, and support needs, ensuring a clear management plan for moving forward.
Comprehensive feedback session
We provide a detailed diagnostic report and a one-on-one consultation to discuss the findings and next steps.
We are proud to say
We meet all of the above criteria
Our autism assessments in London are designed to provide clarity, validation, and access to the necessary resources to support each individual's unique needs..
